in thread mac to IP address?

Ping the broadcast address for your network to fill your arp cache:

# ping 192.168.0.255

where your network address is 192.168.0.0, and your netmask is 255.255.255.0.

Otherwise, arp has only those IPs you talked to.

    Not all hosts will respond to broadcast pings. For example, the Linux hosts respond but the Windows 2000 hosts don't.
